Hey, guys, Justin with AmericanMuscle.com, here with my detailed review of the MBRP Race Catback Exhaust System with Y-Pipe, fitting your 2015 and up Fastback EcoBoost. Now, the Race Catback from MBRP is one of the most popular options for your EcoBoost here on the site and for a few different reasons. For starters, it's currently one of the most affordable options for your ride; it's going to offer full three-inch diameter piping from tip to tip; and finally it sounds really good despite not costing you an arm and a leg.
Now, one thing I personally really enjoy about MBRP is the amount of options they give you in choosing the right system for your ride. For instance, we're looking at the full stainless steel version of the Race Catback here. It's going to cost you a little bit more but not by much. It's going to offer a full lifetime warranty from MBRP, largely in part to the full 409 grade stainless steel construction throughout that's going to do a good job of reducing any surface corrosion.
In addition to that, MBRP does throw two aluminized steel versions of this exhaust at you. One's going to come with black mufflers, black tips, and black piping, and the other's going to be left in that raw aluminized steel silver color. Now, both of those options only carry a three-year warranty, but they're going to be the most affordable.
Now, I did want to spend a little bit of time on tone, because obviously, this is an exhaust after all, and that's a big deciding factor. But a big question I get a lot is: How do I make my four-cylinder EcoBoost Mustang sound good? And honestly, guys, a lot of that is going to depend on what your definition of good is, but what I can tell you is that the MBRP Race is going to deliver a very enjoyable tone, deep, low tone here with practically zero rasp, minimal drone on the highway, definitely not a deal breaker, but you can hear it slightly, and overall, a very, very solid three out of five on my one to five or one to wake the neighbors scale.
Again, you can hear this thing, but it's not going to be totally crazy loud. However, add in your favorite off-road or catless downpipe, and that number would go up considerably.
As for the construction, guys, well, again, I did touch on this earlier, but you do have the full stainless option available to your here. That's the one I have on the table with me, 409 grade stainless. It's going to offer a little better durability over time. It's going to cost you a little bit more, but you do get that full lifetime warranty with the system.
Those two aluminized steel versions, again, great systems. They're going to be a little bit more affordable, but they're only going to carry that three-year warranty, maybe not be as durable when it comes to reducing surface corrosion, but overall, still a great system. You are getting three-inch mandrel-bent tubing from tip to tip with this system, solid welds despite the price, and you are getting the race mufflers, along with the very large four-and-a-half-inch slash-cut tips, etched with the MBRP logo.
You are going to be looking at a simple one out of three wrench difficulty here, guys, when it comes to the install. No cutting or permanent modification needed whatsoever. This is a direct bolt-on part that should make the install a little bit more easy on you. Now, as for tools, well, simple socket set here. You're going to need a large Allen key to tighten up these tips here, but overall, figure about an hour or two in the garage or driveway before you're making some noise.
All right, guys, to wrap up the MBRP Race Catback, I do really enjoy this system for the simple fact that it sounds good; you have some options when it comes to the materials; and it's not going to cost you and arm and a leg to put it on your car. So be sure to check out more from MBRP for your EcoBoost Mustang here at AmericanMuscle.com.

Aggressive Sound and Performance. Now you can give your EcoBoost Mustang a deep, aggressive exhaust note with an MBRP Race Cat-Back Exhaust System with Y-Pipe. This Race Cat-Back has been specifically tuned to get the optimal sound from your 2015-2019 EcoBoost Fastback. This catback not only sounds great, but also improves exhaust flow with the help of the included Y-pipe and high flow mufflers for an increase in RWHP and TQ.

Durable Stainless Steel Construction. Constructed from 3" diameter 409 stainless steel tubing for strength and corrosion resistance, this MBRP Cat-Back Exhaust System features two race mufflers that are completed with 4.5" polished 409 stainless steel slant cut exhaust tips. As an added bonus, the tips are etched with the MBRP logo for true custom styling.

Direct Bolt-On Installation. Engineered to be a direct upgrade replacement for your Mustang's factory exhaust, the MBRP Race Cat-Back Exhaust Kit with Y-Pipe easily bolts up in the stock location with no modifications required.

Application. This MBRP Stainless Steel Race Cat-Back Exhaust is specifically designed to fit all 2015-2019 EcoBoost Fastback Mustangs without the Active Valve Exhaust.

Would I be able to do a muffler delete on this if installed, and would it effect my performance negatively?

If you were do delete the mufflers in the MBRP XP Series Cat-Back Exhaust, it would require tubing to exit the rear of the bumper. We have not tested this kit with a muffler delete to gather any evidence of performance gains or losses.

So i was in the market for an exhaust system and after reading 100s of reviews and 100s of sound clips lol i went with the MBRP Race for my 2017 Mustang EcoBoost. Compared to all the raspy ones ive heard the Race actually has a nice deep tone. Sounds amazing. Considering its half the price of the others and sounds better its worth every penny. Super easy install.

Exhaust sounds much better than stock. Quiet enough to not wake the neighbors in the morning, but still makes a lot of noise when I floor it. There's a bit of drone on the highway, but it's not enough to hinder talking or listening to the radio.

Easy to install, not terribly bad to adjust as long as you take your time and only snug the clamps so you have some movement. Fit and finish was good on the exhaust I got, no fitment issues, I did not have to make any alterations and I do not have a lopsided tip situation due to a hanger being off slightly or anything. Only thing I would say it it would be nice if the mid pipes were marked left and right. It is hard to tell from the diagrams which is which so it takes a short trial and error to figure that out.
Sound is good, its about the same tone as an Maperformance cat back, and my Magnaflow street setup. But with more volume and none of the drone of the MAP setup.
A note about drone, I have read lots of reviews on this site and those who claim its really droney do not know what drone is. I commute 60 miles a day most of it is highway above 2K rpms. There is exhaust note with this cat back, but I would not call it drone by any measure of the word. It is not reverberating, buzzy, or very loud. You can hear the exhaust but you can talk over it normally, it does not vibrate anything, and your radio at 10 or 11 which is moderate will overbear on the exhaust note. With a catted down pipe like stock, you can easily live with this exhaust. Install time took me 1.5 hours in my driveway, part of that time was jacking and getting the car on stands etc. Easy install with two sockets.

Sound is what I was excepted. Does not bother too much, I believe this is pretty enough who wants some sound but does not want to bother others on the street or living area. I recommend this. It fits the car but need to work on alignment. My body shop spent 1.5hours to find correct alignment. I went there 3rd day because while driving it still align itself and touches some under-body metal parts. so you could be experience this ;) Overall I am happy with this product ;)

This is a really great sounding system for the Ecoboost. The exhaust quality is great, it's all stainless steel. Install wasn't hard,i installed it with the help of my brother in about 1,5 hours on jackstand if you use lift, it takes max 20 minutes with correct tools.And absolutely the sound is amazing it gives a very deep tone. Love it.
